Key findings

What ClinicalTrials.gov does not surface for SARS-CoV-2 on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. SARS-CoV-2 is recruiting below its size-band peers.

    5 of 35 indexed trials (14.3%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of SARS-CoV-2 trials is spread across many organizations.

    ModernaTX accounts for 5 of 35 trials (14.3%). 29 distinct sponsors appear on at least one study for this condition label.

  3. Typical SARS-CoV-2 enrolment sits around 245 participants.

    Median target enrolment is 245 among the 35 trials that report a genuine target (sentinel values excluded). 9 of those (25.7%) plan for fewer than 100 participants.

  4. SARS-CoV-2 splits between interventional and observational designs.

    24 interventional and 11 observational studies make up this index (68.6% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
